What Causes Car Window Film to Bubble?

[DeLillian]

The bubbling of car window film may be caused by substandard film quality or improper installation techniques by the workers. Here are some precautions for car window film installation: 1. Sun exposure: After installing the film on the windshield, try to park the car facing the sun during the day to help the film dry faster. It usually takes about half a month for the film to completely dry, including the rear window. 2. Avoid rolling down the windows: For three days after installing the car soundproof and heat insulation film, avoid rolling down the windows. Since there is still moisture between the newly installed film and the window glass, rolling down the windows during this period can easily cause the edges of the film to peel off, and in severe cases, the film may not adhere to the glass again. 3. Avoid car washing for three days: Due to the high water pressure of professional car washing equipment, water can easily seep in from the edges of the windows, increasing the moisture content between the glass and the film. Rolling down the windows within three days can still easily cause the edges of the film to peel off.
